 Any object that you would like to be able to be turned into a badge must implement `BadgeableInterface`.
 
-This interface specifies a single method `getBadgeColour()` and is used to determine what colour the badge should be rendered as.
+This interface specifies a single method `getBadgeColour()` which expects an instance of the enum `BadgeColour` to be returned and is used to determine the colour of the rendered badge.
 
 This method can contain as much logic in it as you'd like to return different colours of badge under different circumstances. EG:
 
 ```php
 // Job.php
 
-public function getBadgeColour(): Badge
+public function getBadgeColour(): BadgeColour
 {
     return match ($this->getKind()) {
-        JobKind::Investigation => Badge::BLUE,
-        JobKind::Interrogation => Badge::RED,
-        JobKind::Shootout      => Badge::BLACK,
-        JobKind::SipWhiskey    => Badge::FOREST,
-        default                => Badge::GREY
